IMPROVEMENT lN SEEDlNG-MACHINES.

Specification forming part of Letters Patent No. 33,664, dated November5, 1861.

To all whom it may concern:

Be it known that I, T. R. RICHMOND, of Massillon, in the county of Starkand State of Ohio, have invented a new and Improved Seeding-Machine;andI do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,forming part of this specification, in which- Figure l is a plan or topview of my invention; Fig.2, a side sectional view of my invention,taken in the linear m of Fig. 1; Fig. 3, an inverted plan of the hopperor seed-box, showing the slides by which the discharge of the seed isregulated, and Fig. 4. a side view of a portion of the invention.

Similar letters of reference indicate corresponding parts in the severalfigures.

To enable those skilled in the art to fully understand and construct myinvention, 1 will proceed to describe it.

A represents a hopper or seed-box, which is placed on a mounted frame,B, parallel with its axle O. The bottom a of the hopper A is perforatedat suitable and equal distances apart with holes I), the upper edges ofwhich are beveled, and directly over each hole I) an agitator, D, isplaced. These agitators are formed of radial arms 0, which are placed ona. shaft, E, said shalt running longitudinally through the seed-box, andhavinga pinion, F,

on one end of it, into which pinion a toothed wheel, G, gears, the wheelG being on a hub of one of the wheels H of axle G.

Directly underneath the hopper or seed-box A there are placed two metalslides, l I,which are placed side by side and notched at their adjoiningedges, as shown at d, the projection eof one slide fitting in the notchd of the other. These notches and projections of the slides formdischarge-apertures e for the seed, and by adjusting these sides, whichmay be done by actuating a single lever, J, the apertures 6 may beenlarged or contracted, as'desired.

The lever J may be secured at any desired point by a set-screw, f, whichpasses through a slotted semicircular bar, 9. (See Fig. 1.) 4

Directly underneath the slides I I there is placed a slide, K, which isperforated at equal distances apart with holes h. This slide K is usedas a cut-off to prevent the discharge of seed from the hopper, thisresult being attained by actuating the slide K, so that its holes h willbe out of register with the apertures e of the slides I I. The slide Kis connected to levers t j, the latter projecting beyond one end of thehopper and connected by a rod, L, to a cam, M, (see Fig. 4,) which isattached to one of the pivots k of a frame, N, behind the hopper orseed-box A.

To the upper part of the frame N there are attached straps O, the lowerends of which are connected to tubes P, the latter being attached byjoints l to arms Q, the front ends of which are connected to the frontpart of the frame B. The lower end of each tube 1? has a tooth, R,attached. These teeth Rform the furrows, and into the upper parts of thetubes P tubes S pass, the latter being stationary and having short tubesT fitting in their upper ends, the upper orifices of the tubes T beingin line with the apertures e of the slides l I.

The operation is as follows The implement is drawn along in the usualway, and the shaft E is rotated from one of the wheels H by means of thegearing F G. The agitators D as they rotate insure the discharge of theseed from the hopper or seed-box A. The discharge of the seed isregulated by adj usting the slides I I through the medium of the leverJ. \Vhen the frame N is in a forward position, as shown in Fig. 2, thetubes 1? are down and form the furrows and the holes h of the slide Kare in line with the apertures 12, so that the seed may fall into thetubes T. 7

When, however, the distribution of the seed is not required, as inturning at the ends of rows and in transporting the machine from placeto place, the frame N is adjusted backward, as shown in red outline inFig. 4, and the tubes P are thereby raised, and the teeth It will beabove the surface of the ground, and at the same time the slide K willbe actuated by the levers ij, so as to cut off the discharge of seedfrom the apertures e of the slides I I.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The arrangement of the slotted cam M, pivot 7c, and adjustable frame Nwith the levers ij, rod L, slide K, straps 0, tubes P, arms Q, and tubesS, all as herein shown and described.
